I am very happy to report, I haven't yet had a child/toddler/infant taken from any of my families in Sims4. Sadly, this wasn't so in Sims3. The teach toddler to speak function came with a very disrupting glitch. The child would get stuck to the floor! Dad couldn't move, either. Mom did her best to care for the infant before she went to work, but there was no way she could free the toddler in order to feed her. It was painful and clearly out of my hands as a player. Both children were taken by SS. This nearly scuttled my Legacy Challenge game, too.
The only time I lost a child in Sims2, was when in my frustration with Sims3, I went back to playing Sims2. Again, a glitch that came with the last pack Mansions and Gardens was never addressed. I had quite forgotten about it until it was too late. I sent the twin boys to school, both exited the castle in which they lived and I turned the camera and my focus on the Mom and toddler sister. Then it happened. As it turned out one of the twins wasn't making it to school. I found him stuck out on the sidewalk unable to get on the bus. Too late to amend the situation, the Social Worker came and claimed all three of the little darlings. I got so angry I immediately uninstalled the entirety of Sims2 from my computer. Sorry I did that now. I had a few choice items from the Store I'll never get back. :'(
But, no, in my fear to lose anymore children from a game as easy and as simple as Sims4, I have resorted very reluctantly to using the Make Happy cheat.
